To all whom it. may concern:

Be it known that I, Gnonos A. Dumas, a citizen of the United States,residing. at Springfield, in the county of l-lampden and State. ofMassachusetts, have invented new and useful Improvements inChocolate-Coating Machinery, of which the following is a specification.

This invention relates toimprovements in chocolate coating machinery. Anobject of the invention is to supply a coating o1 liquid chocolate asdesired, either to the upper surface only, or to the lower surfaces onlyof the cores or creams of the confection. Ii desired the, chocolatecoating may be simultaneously supplied to both the upper and lowersurfaces, that is to say to com pletely coat the cores or creams of theconfection. In some makes or kinds of confections it is desirable tocoat only the upper or bottom surface of the cores or creams. Inmachines now in use the cores are usually flooded from a point above thecores andthe surplus coating material is then blown cit or removed bysuitable air pressure before the completed confections are delivered tothe cooling part of the machine.

The present invention includes a pair or" rotatably mounted disks whichrevolve in a receptacle in which the chocolate coating material isplaced and which material is constantly maintained at a definite temperature for liquefying the same which is alas .t 8'? or 88 degreesFahrenheit. l 'l hen the dislrs are revolved the coating materialadheres to the disks and is carried upwarding woven wire, or reticulatedbelt, on which the cores or creams are placed to be coated. The coatingmaterial is then transferred from these rollers directly to the lowersur-' face of the cores.

It v desired, by the: operation of suitable valves, the coating materialmay be permitted to flowfdownward from the receiving re- Serial No.749,425.

ceptacle directly onto the upper surface of the cream, whereby the uppersurfaces only of the creams will be coated. If desired both the upperand lower surfaces of the creams may be coated.

Referring to the drawings;

Referring to the drawings in detail:

The present invention relates to the structure shown, described, andclaimed in my prior Letters Patent #l,503,527, dated August 5, 192 i,for an improvement in chocolate coating machines in which structurerotatable disks are employed for elevating the coating material.

1 designates the receptacle having the inclined bottom portion 2 inwhich collects the viscous chocolate coating material 3. Any suitablemeansis employed for maintaining the water belorthe bottom 2 at aconstant or definite temperature. at and designate two disks whichconstantly dip into and rotate in the coating material 3. They aresecured to the rotatable supporting shaft 6 which is driven by anysuitable motive power, not shown. 7 designates an endless conveyor whichis composed of woven wire for receiving the creams or cores of theconfection S from the delivery belt 9 at the entrance end of themachine. These cores are placed on the upper strand of the conveyor.Located below the upper strand 7 of the conveyor belt 7 is a tray 10 andmounted for rotation in this tray are the two cylindrical shaped rollers11 and 12, which rollers may be formed with the longitudinal channels orrecesses 13 for the purpose of more eiIicient-ly gathering or collectingthe chocolate coating material indicated at 1-Lt in this tray andcarrying it upward against the lower surfaces of the creams. The tray 10is supplied with the coating material by means of the two spouts 15 and15 which conducts the coating material from the receiving receptacle 16.Scrapers 17 which engage and are located on opposite sides of each ofthe two disks 1 and 5 are provided for removing the chocolate materialtherefrom as these disks, which are located in the chocolate receivingreceptacle 1 is rotated. A detail of one of the disks being shown inFig. 2. Formed in the bottom of the receptacle 16 are the Openings 18,19, and 20 which are shown in the plan view in Fig. 1 and in thesectional view in Fig. 2. 9.1 designates slide valve for opening andclosing the openings 18, 19, and 20. In this valve are formed theopenings 22 and 23 and in the valve 21 is the opening 21. In theposition shown, the openings 20 and 52% are in registration with eachother permitting the coating material to flow directly downward onto thecenter portion 15 of the member 15 the oppositely located ends 15 ofwhich rest directly upon the fixed spouts 15 and 15" and into the tray10 which is located below the upper strand 7 of the endless belt whereit is collected and carried or transferred upward by the rollers 11 and12 against the lower surfaces of the creams. Since the lower side of theupper strand of the conveyor belt 7 contacts with these rollers thecoating of chocolate is forced directly upward through the meshes of theupper strand and directly into contact with the lower surface of thecreams or cores 8, whereby a layer of chocolate will be placed on thebottom surfaces only of the cores. Should it be desired to coat theupper surfaces of the cores, the valve 21 is operated and the openings18 and 22, 19 and 23 are placed in registration with each other when thevalve 21 is moved into the dotted line are attached to the brackets 31.

position 21 thus permitting the upper surfaces of the cores to beflooded as well as their bottom surfaces to be coated. The slide valve21 is operated by means of the rod 25 which is attached thereto foropening and closing the openings 22, 23, and 20 for the purpose alreadystated. The receptacle 16 is adjustably supported in the main casing 1by means of the pins 26 which are located in the vertical slots 27 shownin Fig. 1. Attached to the center portion 15 of the member 15 whichdirects the flow of chocolate from the openings 20 and Ql in oppositedirections onto the spouts l5 and 15 to the forward end of the machineare the rods 33 and 3 1-. The rod 3tis pivotally connected to the crankarm 29 at the point 30. The crank arm is rotatably mounted on a fixedpart 16 of the receptacle 16, as shown in Figs. 52 and 8 by means of thebracket 31. 31 is another bracket which is located in alignment with thebracket 31. Secured in this bracket is a pivot pin 32 on which islocated the link or arm 33; the other end of this link is attached tothe center and swingable part 15 ot' the member 15 which directs theflow of the chocolate from the receptacle 1t; laterally in oppositedirections to the two side spouts 15 and 15. It should be stated andparticularly noticed that the center part 1.3 is the part with theoppositely located s ide spouts 15*, which swings away from the fixedspouts 15 and 15 and is operated by the rod 28. The curved end portions1.3 (see Fig. 3) rest under the two laterally located fixed spouts 13and 15. ll he n the rod 28 is moved inward, as indicated by the arrow28, the center member 15- is swung downward on its two pivots which Thismovement is clearly indicated in Figs. 2 and s by the curved line :35.When this center part 15 is swung rearward by the operating rod 28 thechocolating coating material in the receptacle may now freely llowdownward through the registering openings 2 and directly onto the upperu'fac es of the cores or creams of the contcctions that are to becoated. If desired, the operator may move the slide valve 21 with therod 25 and bring the openings 18 and and 19 and 23 into registrationwith the res' lting effect that the chocolate coating inaterial in thereceptacle 16 will now how downward in three streams onto the uppersurfaces of the confections instead of one. If it is desired to coatboth the upper and lower surfaces of the cores the operator, b means ofthe rod 28, swings or returns the centrally located member 15 into itsoriginal position under the openings '20 and it. The coating materialnow flows through the openings 20 and 2% onto this member at which pointthe stream divides and flows in opposite directions onto the sidespouts- 15 and 15 as indicated by the dotted lines 36 and 37 on Fig. 1and into the receptacle 10, from which it is taken up. i l-it the sametime the coating material is flowing through the registering openings 18and 22, and 19 and 23. By operating the rod 25 the opening 20 may beclosed. I? ow only the upper surfaces of the creams are being coated.

It will therefore be seen that I have provided a very eflicient andsimple construc tion for coating the cores of chocolate confections oneither their upper or lower surfaces only, or, on both of thesesurfaces.
